Fiber optic transceiver BlueOptics 407-BBYC-BO QSFP 40000 Mbit/s

The BlueOptics 407-BBYC-BO is a QSFP fiber optic transceiver offering a maximum data transfer rate of 40000 Mbit/s in a compact silver housing. Designed to be compatible with Dell platforms that accept the original Dell 407-BBYC module, this QSFP transceiver supports high-speed optical links over multi-mode fiber with LC Duplex connectivity and a bidirectional SR2 (BIDI) optical design. The module measures approximately 18.3 mm × 72 mm × 8.5 mm and weighs about 50 g, making it suitable for dense networking environments where space and weight are considerations.

Advantages

The transceiver delivers 40 Gbit/s class performance in a QSFP form factor while complying with MSA mechanical and electrical definitions for interoperability. It implements bidirectional optical transmission suitable for multi-mode fiber and supports digital diagnostics monitoring for real-time status on optical parameters when used in host hardware that provides DDM/DOM support. The lightweight, compact design simplifies installation in switches, routers and storage hardware while maintaining a silver metal enclosure for thermal stability.

Suitable for

• High-speed Ethernet links up to 40 Gbit/s in data centers and aggregation layers
• Fibre Channel over Ethernet and other storage networking applications
• Short-reach multi-mode fiber connections within campus and rack environments (typical ranges up to 100 m depending on fiber and link conditions)
• Interchangeable use in Dell hardware platforms that support the original Dell 407-BBYC QSFP

Key specifications

• Interface type: QSFP
• Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
• Optical topology: bidirectional SR2 (BIDI) over multi-mode fiber with LC Duplex connector
• Typical operational wavelength range (receive/transmit): within the 832–918 nm band (device-specific)
• Form factor dimensions: ~18.3 mm (W) × 72 mm (D) × 8.5 mm (H)
• Weight: ~0.04 kg
• Product colour: Silver
• Supports digital diagnostics monitoring (DDM/DOM) when host hardware supports the feature

How to use

Install the transceiver into a compatible QSFP port on your switch, router or storage device following the host vendor’s hot-plug procedures. Connect LC Duplex patch cords to the module and route the multi-mode fiber to the remote endpoint. Verify link status through the host device management interface and, where available, read DDM/DOM parameters for supply voltage, laser bias/current, transmit output power, receive input power and module temperature to confirm proper operation. Handle the module and fiber connectors using standard ESD precautions and keep protective dust caps in place when ports are unused.

Usage recommendations

For best performance, use high-quality multimode fiber and LC Duplex patch cords rated for 40 Gbit/s operation, ensure compatible hardware that explicitly supports the Dell 407-BBYC QSFP family, and enable DDM/DOM on supported hosts for proactive monitoring. Observe manufacturer guidelines for maximum reach and environmental conditions.
